METHOD OF PRODUCTION OF BLOCK CELLULAR GLASS FROM CRUSHED GLASS Russian patent published in 2014 - IPC C03B19/08 

FIELD: construction.

SUBSTANCE: method of production of block cellular glass includes production of finely ground glass powder by means of grinding of crushed glass, addition of an expanding agent into the glass powder and a binder to produce a cellular glass mixture, granulation of the cellular glass mixture to the size of raw granules of semi-finished product 2-40 mm, foaming of a mixture of raw granules of the semi-finished product in the furnace with crushed cellular glass 0.2-20% of the mass of raw granules of the semi-finished product with production of cellular glass blocks, baking of cellular glass blocks. Raw granules of the semi-finished granules after granulation are dried at 100-450°C and sent to a hopper of temporary storage. Crushed cellular glass of 2-40 mm fraction is selected.

EFFECT: production of an environmentally safe finished product, simplified method of production, preservation of higher crack resistance of produced block cellular glass, making it possible to increase yield of solid cellular glass blocks.
